Description

TECHNICAL FIELD [0001] The present invention relates to a system and a method for constructing a user participatory geographic information system based on block chaining,

The present invention relates to a system and method for constructing a user participatory geographic information system based on a block chain.

The Geographic Inforamtion System (GIS) is an open-source map service that allows users to edit maps freely. It is more up-to-date than commercial map services because anyone can contribute basic maps and themes.

These user participatory geographic information systems are utilized by the US Department of Defense, the US National Geographic Information Agency, NASA, the United Nations, the Ministry of Government Administration and Home Affairs, the National Geographic Information Institute, and the Korea Aerospace Research Institute.

Especially, OpenStreetMap (OSM), which is a representative user participatory geographic information system, follows the Peer Production method like Wikipedia, so that anyone can freely edit and publish the base maps and thematic maps There are advantages.

OSM is used in a variety of commercial software such as Garmin, which is famous for running the Global Positioning System (GPS), Apple Map without Google Maps, and Pokemon High Location based game.

However, such a conventional user participatory geographic information system is difficult to cope with the editing of the intentional intention, and when the high-precision map service is provided free of charge as in the domestic case, the participation rate of users is significantly low.

Furthermore, the conventional user participation type geographic information system has a limitation in that sustainability is degraded because there is no monetary compensation.

The block chain is a technology using Peer-to-Peer (P2P), Decentralized, and Distributed Ledger. In 2008, Satoshi Nakamoto's "Bitcoin: A peer-to-peer electronic cash system" In 2009, concepts and technology were revealed in 50 bit coin transfers.

Currently, block chains are being used not only in currency trading, but also in various fields.

However, in the field of spatial information such as geographic information systems, academic research using the characteristics of block chains has not been conducted. This is because the block chain requires entirely new types of services and technologies that are different from existing technologies, or most of the spatial information technology does not require block chains.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a system for building a user-participated geographic information system according to an embodiment of the present invention.

Referring to FIG. 1, the system for building a user participatory geographic information system stores data relating to a post posted in a block chain-based platform 14 based on a blockchain 12 in the form of a block chain 12, And a geographical information system construction server 20 for constructing a geographical information system in cooperation with the block chain node 10 and the block chain-based platform 14.

Here, the block chain represents a transaction based on a distributed database structure. The block chain comprises a plurality of transaction information blocks, a plurality of blocks are connected as a chain using a hash, Is an algorithm that jointly manages security information by distributing and storing information in digital equipment of a block chain node 10 that is a participant (peer) rather than a central management server in a distributed environment.

Also, a block may represent a unit of information of a transaction occurring in the same time zone. For example, it may correspond to a unit representing transactions to be collected and recorded in one block for a predetermined period of time (for example, a predetermined time from time 1 to time 2).

The block chain-based platform 14 is, for example, a block-chain-based platform as a community platform, allowing a user to create a post through the block chain node 10 via three elements: title, content, and tag. The created post can be retrieved based on the tag.

In addition, the block-chain-based platform 14 allows the user to perform functions such as commenting, sharing, recommending and dismissing via the block-chain node 10.

Accordingly, users can view articles based on tags, and can freely evaluate the quality of posts and whether they are useful or inappropriate for users.

That is, the block-chain-based platform 14 can calculate and expose the rating for each post based on the user's evaluation of each post and the influence of the user corresponding to each evaluation.

In addition, the block-chain-based platform 14 allows to provide or reduce monetary compensation based on the user's evaluation of the post.

The block-chain-based platform 14 is configured to determine whether or not each post contributes to the construction of a geographic information system (that is, when the object to be displayed is extracted from each post and reflected on the map as described later) To provide additional monetary compensation.

For example, additional monetary compensation may increase in proportion to the time period reflected in the map.

Thus, by providing additional monetary compensation based on the period reflected on the map, it is possible to encourage users to compete to publish accurate information and induce voluntary updates so that each post is reflected on the map for a longer period of time .

The block chain-based platform 14 operates on a block chain basis, so that it is impossible to edit and delete posts and comments. Alternatively, the platform 14 based on the block chain may be implemented such that posts and comments are deleted for a preset period of time. At this time, edited and deleted posts and comments may still be recorded in the blocks constituting the block chain .

The block chain-based platform 14 may provide three monetary compensation to users. For example, the block chain-based platform 14 may provide a first token indicative of the influence within the block-chain-based platform 14 and a second token tradable through the physical currency. Here, the first token and the second token may be exchangeable with each other.

At this time, the influence in the platform 14 based on the user's block chain can be determined based on the first token.

The block chain-based platform 14 may provide the first token to the creator of the post based on the user's evaluation of the post and the influence of the user corresponding to each evaluation.

That is, the amount of the first token can be determined according to the influence within the platform 14 based on the block chain of the user who evaluated the post.

The block chain-based platform 14 may use the Delegated Proof of Stake (DPOS) algorithm. In order to utilize the block chain, we solve the limitation that the mining is inevitable and do not require a fee to the users. By increasing the amount of virtual money through inflation, we can provide financial compensation to users through means other than mining. And the like.

Alternatively, the block chain-based platform 14 may use a Proof of Stake (POS) algorithm and a Proof of WorkLow algorithm.

The block chain node 10 is an object storing the blocks connected to the block chain 12 in the security area of the memory or storing them in the security area of the database, and a control unit for executing an application program.

The block-chain node 10 may include a notebook PC, a desktop PC, and a mobile terminal capable of wired / wireless communication. The mobile terminal is a wireless communication device that is guaranteed to be portable and mobility and can be used not only for a smartphone, a tablet PC, a wearable device, but also for a Bluetooth (BLE), an NFC, an RFID, an ultrasonic, WiFi), and LiFi (LiFi). However, the block-chain node 10 is not limited to the form shown in FIG. 1 or to those exemplified above.

The block chain node 10 is responsible for storing data relating to the posts posted on the block chain-based platform 14, such as the title of the post, the content of the post, the tags of the post, comments left on the post, Blocks in which the number of shares of the post can be recorded can be stored.

The posts posted on the block chain-based platform 14 may include geographical information including pre-set tags and spatial information data of a predetermined format as data for building a geographical information system. For example, the predetermined format may be GeoJSON format.

The Geo-Jason format is a spatial data exchange format based on JavaScript Object Notation (JSON), which supports Feature Collection, Geometry, Feature, and follows Request for Comments 7946 (RFC 7496).

By using the Geo-Jason format, unlike the XML-based GPX (GPS Exchange Format), it is free from various constraints, and thus the same data can be stored in a small capacity.

In addition, the Geo-Jason format is text-based, which makes it easy for both people and machines to read, and is highly programmable and platform-independent.

Also, it is a format that uses the syntax of JavaScript, so it is useful to use it in a web environment that mainly uses JavaScript. The types of Geomtery in Geo-Jason format include Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, GeometryCollection and represent nodes through coordinates. The feature represents the color and properties of the object.

That is, the data on the post may include predetermined tags, data in the Geo-Jason format, and contents of the posts.

The block chain-based platform 14 may provide an editing tool for generating spatial information data in a predetermined format. Users can select locations for building geographic information systems and easily record buildings, structures, roads and traffic routes through editing tools.

The block-chain-based platform 14 can automatically convert the information recorded in the editing tool into the Geo-Jason format, which is a predetermined format.

The geographical information system construction server 20 can establish a geographical information system in cooperation with the block chain-based platform 14.

The geographic information system construction server 20 may receive data regarding the posts including geographic information from the block chain-based platform 14. [ For example, the geographic information system construction server 20 may receive data relating to a post including geographic information from the block-chain node 10. [

Here, the geographical information may include a predetermined tag and spatial information data of a predetermined format.

The geographical information system construction server 20 can perform at least one data extraction process by performing data handling on data related to a post.

The geographical information system construction server 20 can display the object to be displayed on the map.

The network 22 is a connection structure capable of exchanging information between nodes such as terminals and servers. The network 22 may be a local area network (LAN), a wide area network (WAN), a wide area network (WAN) WWW: World Wide Web), wired / wireless data communication network, telephone network, wired / wireless television communication network, and the like. Examples of wireless data communication networks include 3G, 4G, 5G, 3GPP, LTE, WIMAX, Wi-Fi, Bluetooth, infrared, Communications, Visible Light Communication (VLC), LiFi, and the like.

2 is a block diagram of a geographical information system construction server according to an embodiment of the present invention.

2, the geographical information system construction server 20 may include a post data receiving unit 200, a handling unit 210, an exposing unit 220, an updating unit 230, and an evaluating unit 240 .

The post data receiving unit 200 may receive data relating to a post including geographic information from the block-chain-based platform 14. [

The post data receiving unit 200 may sense blocks generated in real time and retrieve data.

For example, the post data receiving unit 200 can retrieve a block including data related to a post including the geographical information from the block chain node 10 in real time, and extract a post including the geographical information from the block .

Here, the geographical information may include a predetermined tag and spatial information data of a predetermined format.

At this time, the predetermined format may be GeoJSON format. The predetermined tag may include the text promised in the block chain-based platform 14 in advance. Figure 3 shows the data of the Geo-Jason format included in the posts posted on the block-chain-based platform 14.

That is, the data on the post may include predetermined tags, data in the Geo-Jason format, and contents of the posts. Here, the data and post content of the Geo-Jason format are described in the first area of the post, and the predetermined tag can be described in the second area of the post.

The post data receiving unit 200 can quickly select only the data necessary for constructing the geographical information system through the predetermined tag.

The handling unit 210 may perform data handling on the data relating to the post.

Specifically, the handling unit 210 may crawl the text (contents of the post) described in the first area of the post and perform data handling on the crawled data.

At this time, when the text is crawled from the post, the text is put into a single variable, and html tags such as a block chain-based platform, that is, a community automatically generated upon creation are inserted, You can not use the data right away from the rules of the Jason format.

That is, since the crawled data is created based on HTML, data handling such as removing HTML tags can be performed.

Accordingly, the handling unit 210 can search for embedded html tags such as < >, < > in the corresponding variable through the loop, and convert the corresponding positions into spaces so as to be used as the exposing data.

4, the handling unit 210 is shown performing data handling to remove <p>, </ p> and </ p> from the crawled data.

The display unit 220 can re-convert the handled data back to the Geo-Jason format.

The display unit 220 can extract the object to be displayed from the data of the re-transformed Geo-Jason format. Here, the display target object may include a specific place, a building, a structure, a road, and a traffic route to be displayed on the map.

Also, the display unit 220 can extract location information (latitude, longitude, address, lot number, and the like) from which the object to be displayed is to be displayed, from the data of the re-converted Geo-Jason format.

The display unit 220 can display the display object at a position corresponding to the position information on the map.

The display unit 220 can connect the display target object on the map with the publication information about the publication and display the publication information together with the display target object.

Here, the posting information includes the link of the post, the influence of the author of the post, the title of the post, the content of the post, the tag tagged in the post, the comment left in the post, the recommendation number of the post, .

Accordingly, it is possible to obtain credibility by allowing users to confirm various information about each object to be displayed, and to move to a corresponding post and to leave an evaluation or a comment.

Specifically, the display unit 220 extracts feature information including a geometry object and attribute information from Geo-Jason format data, feature collection information including a plurality of features as a set of features, Point, Linestring, Polygon, Multipoint, MulltLineString, MultiPolygon, GeometryCollection.

The display unit 220 can display the display target object using the feature information, the feature set information, and the geometry information.

For example, the display unit 220 can arrange only the n points according to the type and coordinates, or can arrange the n lines to be arranged on the specific coordinates.

Then, the display unit 220 can perform drawing according to a predetermined framework.

That is, the display unit 220 can arrange the coordinates through the data of the Geo-Jason format, and perform drawing with another image according to a predetermined framework.

The update unit 230 may update the map of the geographic information system by monitoring the posts of the block chain-based platform 14. [

The update unit 230 may update the map of the geographic information system by comparing the ratings of the posts including the same location information.

The update unit 230 receives the data related to the post (second post) by the post data receiver 200 and displays the position information (latitude, longitude, address, lot number, etc.) It is possible to determine whether an object exists in a position corresponding to positional information on the map.

If the object does not exist at the position corresponding to the position information, the update unit 230 may update the map by displaying the object to be displayed at the position corresponding to the position information on the map through the exposing unit 220.

Alternatively, if there is an object at a location corresponding to the location information, the update unit 230 updates the rating of the first post used for building the current object and the rating of the second post received by the post data receiver 200 Can be compared.

If the score of the first post is high, the update unit 230 does not update the map. If the score of the second post is high, the update unit 230 reads the position of the second post from the second post The map can be updated by displaying the derived object to be displayed.

The evaluation unit 240 may receive a user's evaluation or comment on each of the display target objects from a user terminal (not shown).

The evaluating unit 240 may transmit the evaluation of the user to the block chain-based platform 14 so as to be reflected in the rating of the corresponding post.

As described above, the present invention is advantageous in that users can perform evaluation of contents and thus can provide monetary compensation to the producer without monetary consumption of the users, thereby increasing the reliability of each contents.
